How to unlock the Best Friends Forever achievement in FIFA 14 - Definitive Guide
Start an Online Friendlies game, invite your friend and play the 4 required games for the season.
Win, lose or draw you will earn this at the end of the 4 games.
*UPDATE*
"Actually, you don't have to play 4 games.
It's only 3 matches and you can quit 'em all. My opponent scored an own goal and quit after the 5 minute mark for all 3 matches and we both got the achievement.
To be fair, I checked the solution for the Xbox 360 version of the game and I can confirm that, that method works for the Xbox One."
Thanks to Why So Jealous for the update.

Ok below is a method I copied from TRueAchievement. If you don't like the idea of quitting the games then don't.
This literally takes 3 minutes, and 3 matches - just be sure that all three are with the same "friend".
From the main menu in FIFA 14, L1 or R1 to the "Play" tab. Select the "Online Friendlies" tab.
Select a friend from the list on the left of the screen. Press A twice to invite them to a friendly. (Don't worry about the settings, just leave them at default.)
Once the match starts kickoff, wait a few seconds and then quit. (You don't have to wait through 5 minutes of "game" clock - you can just quit immediately.)
Do this twice more with the same "friend".
That's it. Those three games you quit give your friend the Friendlies season title and you both get the achievement.
Like I said: super easy, super quick.
Have fun!!
Nothing difficult here either. Find the Online Friendlies tile in the Play tab on the Menu and invite a friend. You can quit the first 2 matches after 5 minutes, but the 3rd one has to be finished. Set is to 2 minute halves to do it the quickest.
If you want to boost, please use the Achievement Trading Thread.
A season in Online Friendlies consists of 5 games, and so the quickest way to earn this is to have one person win 3 games. From the main menu, press on the "Online Friendlies" tile. Invite a friend, and swap the half-length to 2 minutes. The person who will be losing can back out of the first 2 games to hasten the process, but the 3rd match must be played to completion.
After 5 minutes of the match we leave. Repeat three times and both get a trophy.
